In the past 100 years, double twisted hexagonal gabions, mat is widely used in revetment, slope protection, river, rock fall protection and other aspects of gabion very bottom of its costs to meet the requirements of all users now it has been the agent of the government and the private ownership of land owned by individuals accepted. With extensive gabion should be shipped in the United States, its technical standards and product quality have been put on the agenda. As the United States the highest standards of ASTM Standards introduced a specialized testing hexagonal gabion quality standards ------ ASTM A975-97.
